Nanoconfined polymer electrolytes

This project probes the physical properties of polymeric materials when confined within nanometer-scale volumes. We used grazing-incidence X-ray photon correlation spectroscopy to establish that the nanoscale viscosity of a polymer melt, as probed by gold nanoparticle tracers, is substantially boosted under nanoconfinement. Our experiments have taken advantage of recent instrumental improvements at the CHX X-ray beamline at the National Synchrotron Light Source II to increase the signal-to-noise, and extend the range of accessible timescales.
